I wore this suit in for four days total (Two weekend meets) and by the end of the forth day, it was ripped on the inside. The core-stablizer lining was apparently glued to the other piece of fabric and it did not hold well at all. It's unfortunate because I really liked the fit and style of this suit. I would suggest you save [$] and just get the Flyback training suit speedo endurance. It's exactly the same material and style, it just doesn't have the core-stabalizer (which didn't really make that much of a difference from what I could tell) in it.
